TileMapLayer: Allow getting TileSet's source_id by tile's name [Idea]

[GodotHatesMe]

I have a huge tileset. All my tiles have a specific name, which is used by my map drawing gdscript that draws a map dynamically based on data. Each tile data contain a tile name (for example "AAA").

Right now, to get the name we have to do something like this, which can slow down the drawing:

var source_id := get_or_create_tile_source(tile_data["id"])
set_cell(cell_pos, source_id, Vector2i.ZERO, transforms)

func get_or_create_tile_source(tile_id: String) -> int:
	for source_id in tile_set.get_source_count():
		if tile_set.get_source(source_id).resource_name == tile_id:
			return source_id
			
	return 0

This could be faster and shorter if we could just pull a source id by tile's name.

I don't know a better way, but what are the shortcomings of dictionaries in solving this problem?
